146 Dr. J.C. Warren on the Osteology and Deniition of 
leton of another Mastodon giganteus had been discovered in the 
town of Newburgh, State of New York, about six miles from the 
bank of the Hudson river (in the same town, but not on the same 
spot, from which the skeleton set up by Mr. Peale was obtaimed 
in the beginning of this century), and that it was in every respect 
more perfect, and perhaps larger than any one yet found. It is 
worthy of remark, that of five existing specimens of Mastodon, 
three have been exhumed in the contiguous States of New York 
and New Jersey ; two of them from the same town. Only two or 
three Mastodon bones have been discovered in any part of New 
England. The Baltimore skeleton was excavated in the State of 
Ohio, and the Missourium of the British Museum from the State 
of Missouri. 
After the specimen from Newburgh fad been articulated, it 
was exhibited in the city of New York during the past autumn, 
and was subsequently brought to the vicinity of Boston by the 
proprietor, Mr. Brewster. Having satisfied myself of the per- 
fection and the great value of the bones, with a view to the promo- 
tion of science ‘and from a conviction of the great injury which 
would be done to the skeleton by public exhibition in various 
places, I made offers for its purchase, which were accepted. This 
invaluable specimen is now my property, and as a duty to sci- 
entific men who are interested in the subject, I shall feel myself 
called on to describe it particularly at a future time in connexion 
with the New Jersey skeleton. , 
As the bones were articulated in a manner different from what 
seemed to me exact, I have had them separated with a view to a 
new arrangement, founded on the strictest anatomical observa- 
tion. The skeleton appears to be about twelve feet high, and 
some idea of the size of its parts may be formed from the fact, 
that the head is three feet long without the tusks, which were 
ten feet in length. These dimensions have, however, diminished 
since the bones were first exposed to the air; the pelvis, for ex- 
ample, which measured six feet two inches at first in its transverse 
diameter, now measures six feet. The comparative length of the 
tusks and of the diameters of the pelvic apertures are characters 
from which I have inferred the New Jersey specimen to have been 
a female, and my own very probably a male. 
The whole head with its teeth is perfect, as is the whole ver- 
tebral column, consisting of seven cervical vertebrae, twenty dor- 
sal, three lumbar, and the os sacrum. A solid sternum exists, 
the posterior part of it only being deficient. The ribs, twenty in 
number, are perfect. The bones of the pelvis are co-ossified,—a 
fact which would lead to the suspicion of the animal having been 
aged; but on the other hand, the epiphyses, although co-ossified 
with their bones, yet generally exhibit traces of separation. The
